Lumifinder™ Supports Quantification and Graphing of Measurement Results for Laparoscopic Surgery

TOKYO, Japan –November 7, 2023 – Advantest Corporation (TSE: 6857) today announced a new fluorescence detection system, the Lumifinder™ (product code: MED7100), for laparoscopic surgery.

During laparoscopic surgery, the Lumifinder™ irradiates the observation site, to which a contrast agent (indocyanine green) has been administered in advance, with a near-infrared laser beam. The intensity of the resulting fluorescence is displayed numerically and graphically, providing quantitative data for better real-time decision-making. Fluorescence intensity spectrum waveforms and changes in intensity can also be observed. In addition, the Lumifinder™ can connect to the laparoscopic camera video signal, enabling medical staff to observe fluorescence while checking the laser irradiation position visually.

  • Lumifinder™ Fluorescence Detection System

The Lumifinder™ is the first medical device Advantest has released in its approximately 70-year history (medical device approval number: 30500BZX00031000). It will be introduced at select medical institutions in November 2023 and is scheduled to be provided on a lease basis to general medical institutions in Japan from April 2024. Please note that at present, it can only be used within Japan.

Product Overview

The Lumifinder™ emits a guide light and a near-infrared laser from the tip of the scope. The position of the guide light is confirmed using a laparoscope, and the Lumifinder™ displays the changing fluorescence intensity at the relevant site in real time. A spectroscopic sensor is used for measurement, and the generated fluorescence is digitized and displayed graphically. It is also possible to import laparoscopic images and display them side by side with the measured fluorescence spectrum and graph of fluorescence intensity changes.


  • Displays fluorescence intensity numerically and graphically in real time
    Enables medical staff to make judgments based on clear numerical standards, eliminating the ambiguity inherent in images. Fluorescence intensity spectrum waveforms and changes in intensity can also be observed.
  • Full suite of display capabilities
    Information can be displayed in many different ways, including spectrum display, color bar display, peak value time change graph, and laparoscopic images.
